Get ready to enter into a freaky nightmare where nuns, yes nuns are the enemy! Not just any nuns, but flying alien nuns are trying to land and snuff out human existence. Nuns will exit the Mother Superior ship and try to land. You must shoot them down and protect the innocent. They will come quickly so your shots must be fast and accurate. Just use your mouse to aim and click to shoot. Your clicker finger is about to get the workout of a lifetime, so stretch it out before you begin. You wouldn't want to injure yourself. Survive the invasion by outlasting the nuns. Monitor your progress by viewing your health meter and the health meeter of the mother ship.
